[0030] It should be noted that a centrifugal fan is provided in the housing 1 , and an extraction end of the centrifugal fan is fixedly provided with the pneumatic suction nozzle 24 . The centrifugal fan is started to enable the pneumatic suction nozzle 24 to extract the debris generated when the drill bit 23 drills and mills the workpiece.

[0031] It should also be noted that the linear drive 21 is configured as a cylinder, which is fixedly arranged in the housing 1; the rotary drive 22 is configured as a motor, which is fixedly arranged on the output shaft of the linear drive 21; the linear drive 23 is configured as a motor, and a threaded rod is fixedly arranged on the output shaft of the motor, and the threaded rod is threadedly connected to the sliding seat 32; the rotary drive 234 is configured as a motor, and the output shaft of the motor is fixedly arranged on the auxiliary seat 35; the rotary drive 33 is configured as a motor, and the saw blade 37 is fixedly arranged on the output shaft of the motor.

[0032] The specific implementation scenario is as follows: place the workpiece to be processed between the two positioning plates 62, drive the two positioning plates 62 to approach each other, and position the two ends of the workpiece through the positioning plates 62. If drilling and milling operations are required on the workpiece, the output shaft of the linear driver three 52 drives the shell 1 to move horizontally. When the drill bit 23 is located directly above the position to be drilled in the workpiece, the shell 1 is driven to move vertically downward through the output end of the linear driver four 53, and at the same time, the rotary driver one 22 is started. The rotation of the output shaft of the rotary driver one 22 drives the drill bit 23 to rotate. When the drill bit 23 contacts the workpiece, the drilling operation on the workpiece is realized; if cutting operation is required on the workpiece, move the saw blade 37 to directly above the position to be processed of the workpiece, and then start the linear driver two 33 and the rotary driver three 36. The linear driver two 33 drives the saw blade 37 to move vertically downward, and the saw blade 37 rotates and contacts the workpiece to realize cutting of the workpiece.

[0033] Compared with the existing technology, drilling, milling and sawing processes are completed on the same equipment, which avoids the time waste of frequent equipment replacement and greatly improves the processing efficiency. It also integrates drilling, milling and sawing functions in one, reduces the number of equipment and occupied space, and reduces equipment costs.

[0034] Refer to the instruction manual Figures 1 to 7For some non-rigidly connected pipes, such as ventilation ducts, square tubes with a little elasticity are used to facilitate installation and reduce noise transmission. The square tube profile has the characteristics of flexibility and elasticity, and can return to its original shape after being deformed by force. The square tube usually needs to be customized according to the design requirements of the specific vehicle model to adapt to different installation sizes and shapes. Therefore, the square tube needs to be cut and processed and installation holes need to be opened. Since the square tube is flexible and elastic, when it is cut with a saw 37 or drilled with a drill 23, the drill 23 and the saw 37 will produce an extrusion force on the square tube in the initial cutting stage, causing a slight concave deformation at the incision of the square tube, resulting in an uneven cutting of the square tube and insufficient processing accuracy, which is not conducive to subsequent welding and other processing of the square tube. In order to solve the above problems, specifically, an auxiliary correction component 7 is provided on the support station 4, and the auxiliary correction component 7 includes two correction seats 72.

When the drill bit 23 is located in the auxiliary hole, the drilling of the workpiece is completed; when it is necessary to cut the workpiece, the two correction seats 72 are driven close to each other, and the area between the two correction seats 72 is a cutting area, so that the saw blade 37 is located above the cutting area, and then the saw blade 37 is driven to rotate and move toward the workpiece, so that the saw blade 37 completes the cutting of the workpiece in the cutting area. During the drilling and cutting process, the correction seat 72 is used for support to avoid depressions in the drilling or cutting area of ​​the workpiece.
